Quantum Mechanics

Postgraduate course

Course description

Objectives and Content


PHYS201 offers a systematic introduction to fundamental non-relativistic quantum mechanics.


The course introduces Schrödinger equations with solutions in simple potentials, including

harmonic oscillator, spherically symmetric potentials with hydrogen-like atoms. Axioms of quantum mechanics are introduced; matrix representation of quantum mechanics is discussed together with approximate methods (the variational method, perturbation theory, Born approximations). Program also covers spin and angular momentum representations and addition rules and identical particles treatment.
